To a'ZZ whom it may concern:

Be it known that I, ROBERT J. BALZ, a citizen of the United States, and resident of Syracuse, in the County of Onondaga, in the State of New York, have invented new and useful Improvements in Internal-Combustion Engines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvenients in internal combustion engines, and reters more particularly to the structure of the base as a division of my application, Serial No. 830,(310, filed Apr. 9, 1914:.

The main object is to provide the base of the engine with a plurality of non-communicating conpartments which are liquid tight for containing. respectively, the lubricating oil, the liquid fuel and the battery for ignition purposes.

Another object is to extend the cam shaft forcontrolling the operation of the fuel inlet and exhaust valves across the oil chamber from side to side, and to provide said cam haft with an interior oil chamber comniunicating with the oil reservoir in the crank case, so as to cause the oil to be distributed through said shaft to the various parts and mechanisms which need lubrication.

Other objects and uses will be brought out in the following description.

In the drawings Figures 1 and 2 are vertical sectional views, taken at right angles to each other through the base of the engine, showing the several compartments for the oil, liquid fuel and battery.

The' base of the engine comprises a lower section 1- and an 'upper section 2- meeting in a plane substantially coincident with that of the axis of the crank shaft as 3- the lower section being divided by partitions -4-, and 6- into a series of non-conmunicating compartments -7-, 8- and -9-. The compartment 8-- is located' below the compartnent -7- and to one side of the compartment 9 and constitutes a liquid fuel reservoir extending from side to side of the base, and provided with an inlet -10- through which liquid fuel may be supplied, said inlet being normally closed by a plug or cap -11--.

The chamber -7-- constitutes an oil reservoir located above the chamber -`8- and connunicating with the cylinder'of the engine and may be supplied With oil through either of a pair of oppositely arranged hand-holes 12- closed by plates'-l3-. The compartment -9- constitutes a battery chamber opening through the outside of the base through a hand-hole -14-+ which is normally closed by a plate -15-, all of said plates 13- and 15- being Secured to the corresponding sides ofthe base to form liquid and air tight joints. the chamber -9- being adapted to containany suitable form of battery, as a for ignition purposes and is provided with an opening -16- in one of its end walls for permitting the passage of the electric wires therethrough. A ho llow cam shaft 17- is journaled in suitable bearings -18- in the opposite sides of the base and is provided with a central lengthwise opening 19 communicating through one or more radial openings -20- with the interior of the oil chamber -7-, said cam shaft being extended across the interior of the oil chamber and is provided with cams 21- for Operating suitable rock arms 22- by which motion is transmitted to the inlet and exhaust valves, not shown, through the medium of rods -23-.

A suflicient quantity of oil may be maintained in the oil chamber -7- to cover the timer shaft +17- so as to cause the oil to flow into the passage -19- in said shaft from which it will bedischarged under centrifugal force through the radial passages -20- to various parts of the mechanism within the crank case which require lubrication. The timer-shaft may be driven from the crank shaft not sho-wn,'by any suitable power transmitting mechanis'm. An oil pump 25- is located within the oil chamber 7- and driven from the timer shaft -17- by suitable gears 26- for forc'ibly feeding the oil from the reservoir --7- to the interior 'of the timer shaft, but this feature is claimed more particularly in my pending application, Serial No. 8,963, filed Feb. 17,- 1915.

Secured to one side of the liquid fuel .chamber is a force feed pump *27 which communicates through a pipe -28- with the interio'r of said chamber and constitutes a part of a force feed mechanism forming which are normally` the subject-matter of my ending application, Seria] No. 8,965, filed Feb. 17, 1915. The main feature, however, of my present nvent'on is the division of the base of the engine into a series of non-eommunicating conpartments for forming reservoi's for the lubrcatng oil, lquid fuel and the battery, respectvely.

What I claim is:

An internal combnston engine having a hollow base divided into a phrality of nonconnnunieatng conpa-tnents, one of the compartnents consttuting an oil chamber,

another compartnent, a liquid fuel Cham bel', a thrd compa'tnent, a batte'y chamher, and a hollow cam shaft extending across and jou'naled in opposte sides of the oil ehanber and provided with 'adal passages connecting the interier of the hollow shaft with the oil chamber.

In witness whereof I have hereunto set my hand this 8th day of 1 `eb'uary,` 1915.
